ELTEC was the brainchild of Phil Snowdon, however prior to that he was involved with Contel and Thespak. These two later merged to become Contel Thespak in Stroud. For a short while they merged with CCT but that was very short lived. Thespak were the original designers and manufacturers of the Mark 1 Strand Mini II dimmers.
